To determine the bandwidth, you subtract the start frequency from the end frequency. Here, the start frequency is 6 MHz and the end frequency is 18 MHz.

Calculating the bandwidth involves the following:

Bandwidth = End Frequency - Start Frequency

Bandwidth = 18 MHz - 6 MHz

Bandwidth = 12 MHz

Thus, the bandwidth between 6 MHz and 18 MHz is indeed 12 MHz. This reflects the range of frequencies that the signal can use, which is crucial in contexts such as telecommunications and broadcasting, where managing frequency ranges efficiently is vital for avoiding interference and maximizing signal quality.
